- Letters Patent No. 84,326, dated November 24, 1868; antedated M04 25, 1868.

MROVED JOURNAL-BEARING- IQR RAILROAD-CARS.

The Schedule referred to in these Letters Patent and making part of the same.

1'0 all whom it'ma y concern:

Be it known that I, 'ISAAG P. WENDELL, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and improved J ournal-Bearing for Baih'oad-Oars; and I do hereby declare that the following is afull and exact description thereof, reference being'had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists of journal-bearings for railroad-cars, connected with an oil-chamber, and openings leading therefrom to the concave surface of the bearing, and supplying the journal with oil by means of capillaryattraction, as hereinafterdescribed.

In the accompanying drawings, which make a part of this specification Figure 1 is a plan or top view of the improved bearmg.

Figure 2 is a vertical longitudinal section of the same.

Figure 3 is a cross-section.

Figure 4 is a horizontal section at the line a: x.

Like letters in all the figures indicate the same parts.

A is the improved bearing, whose upper surface is made of such form as to conform to the surface of the journal-box.

The piece is cast'with a chamber, B, to contain the oil for lubricating the journal.

The requisite strength of the bearingis preserved by making its central part solid, as represented in thedrawings. Other solid parts in the area of the oilreservoir may be made without decreasing too much material, in the chamber B, and extend them through slide into place between dovetails, or be made to drop into the openings.

An extension may be made at one end of the bearing,-for filling it with oil, and without removing the bearing.

It will readily appear that the oil will be carried to the journal by capillary attractioh through the cord 1), so as to supply the journal with oil in a very even manner, no more passing through it than is necessary for the lubrication, in consequence of the journal being always against the face of the bearing, the cord, which fills the tubes 0, being sufliciently tight to prevent a too rapid flow of oil.

I do not claim, broadly, oil-chambers and tubes, or the porous cords above the-bearings of axles, as such have been known and used before; but

What I claim as new, and desire to secure by Letters Patent, is

The journal-bearing A, constructed with an oilchamber, B, and tubes or openings, 0, which are provided with -'a cord, D, or other fibrous. material, substantially in the manner and-for the purpose set forth.

In testimony that the above is my invention,.I have hereunto set my hand and aflixed my seal, this 2d day of March, 1868.
